Bert Allen Mann, who went by Allen, was found brutally bludgeoned and stabbed to death in his Austin, TX home in 1994. There were a limited number of viable suspects, ranging from known burglars to jealous love triangle participants.  Despite ample suspect blood found at the scene, the case went cold. Austin PD’s cold case unit finally turned to IGG to learn the name of the person who had killed Allen in a bloodbath in his foyer, and they were surprised to learn he was not in the case file.  And, he slipped through their fingers before they could ensure justice for Allen.

You are not going to want to miss this DOE: ID episode!  Jane Does found days apart in Kern and Ventura Counties were linked by DNA and their killer prosecuted – even though no one knew their names.  IGG analyses took years, scores of volunteers, and one of the largest family trees ever constructed by the DNA Doe Project.  The women were finally identified as Shirley Soosay and Maricela Rocha Parga. The episode also features an exclusive interview with DDP team leader Rebecca Somerhalder. 

15 year old Melissa Lee was home alone in 1993 when someone kicked in the door and drugged her, abducted her, and killed her.  The prime suspect, her boyfriend, had threatened to kill her that very day, and police believed he made good on that threat. But they could not build a solid case, and Melissa’s murder remained unsolved.  Three decades later, IGG pointed the cold case investigators right back to the case file, and someone in Melissa’s life – someone other than her boyfriend.  Luckily, Alan Dean was apprehended alive, and justice for Melissa was served at long last.
